The Effect of Resistance Exercise on All-Cause Mortality in Cancer Survivors.
examine the independent associations of leisure-time aerobic physical
activity (PA) and resistance exercise (RE) on all-cause mortality in
PATIENTS AND METHODS:
2863 male and female cancer survivors, aged 18 to 81 years, who
received a preventive medical examination between April 8, 1987, and
December 27, 2002, while enrolled in the Aerobics Center Longitudinal
Study in Dallas, Texas. Physical activity and RE were assessed by
self-report at the baseline medical examination. Cox proportional
hazards regression analysis was performed to determine the independent
associations of PA and RE with all-cause mortality in participants who
had a history of cancer.
Physical activity in
cancer survivors was not associated with a lower risk of all-cause
mortality. In contrast, RE was associated with a 33% lower risk of
all-cause mortality (95% CI, 0.45-0.99) after adjusting for potential
confounders, including PA.
participated in RE during cancer survival had a lower risk for all-cause
mortality. The present findings provide preliminary evidence for
benefits of RE during cancer survival. Future randomized controlled
trials examining RE and its effect on lean body mass, muscular strength,
and all-cause mortality in cancer survivors are warranted.
